Bug ID: 112071 Summary: 5700 XT: ppfeaturemask doesn't work with iGPU multi-monitor Product: DRI Version: DRI git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: minor Priority: not set Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: zamundaaalp@gmail.com
If the BIOS option "iGPU multi-monitor" is enabled (so I can use the internal GPU ports, namely DVI) amdgpu.ppfeaturemask doesn't do anything anymore. "cat /sys/module/amdgpu/parameters/ppfeaturemask" gives the mask I set (either fffd7fff or simply 0xffffffff) but the files like /sys/class/drm/card0/device/pp_od_clk_voltage don't actually get created. They do if I disable iGPU multi-monitor.
Wether I'm on kernel 5.3.6 or 5.4rc2 doesn't matter, wether I'm on Mesa 19.2 or 19.3 (git) doesn't matter as well.

--- Comment #5 from zamundaaalp@gmail.com --- I am really sorry. I completely overlooked that my external GPU might simply be card1 and the internal one card0. Because that's the case. The files are all there in /sys/class/drm/card1/device/ like expected.
